INTRODUCTION Tympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients. OBJECTIVE The aim of...

OBJECTIVES To assess whether there is an association between high lactate concentration in amniotic fluid (AF) and labor dystocia. DESIGN Prospective observational study. SETTING Labor ward at General South Hospital, Stockholm, Sweden. POPULATION AND METHODS Women in active labor attending labor ward, having at least two consecutive measurements of lactate concentration in AF, measured 60...

A 5-year-old boy underwent orthotopic liver transplantation (OLT) for cirrhosis secondary to tyrosinemia. His immediate post-transplant course was unremarkable. After five months, he developed fever (T >38 °C). At that time, he was receiving tacrolimus, cellcept and prednisolone. His laboratory findings revealed an ALT of 85 IU/L, AST 86 IU/L, Alk-P 730 IU/L, total billirubin of 2.5 and direct ...

In this study, an integrated ecological system was constructed to treat small scattered aquaculture wastewater in southern rural areas of China. The water outlet 4 level wetlands continuously monitored from July December 2017. Results showed the average concentrations total nitrogen (TN), ammonia (NH + -N), nitrate (NO 3 phosphorus (TP) and chemical oxygen demand (COD) were 43.64mg/L, 17.53mg/L...

In HeLa cells cultured in a medium containing 142 mequiv./l. sodium ions only the mitotic forms are birefringent (anisotropic index, 27/1000). In a culture medium containing 155-160 mequiv./l. sodium ions, large numbers of nuclear forms reminiscent of the prophase were found. In such a medium the anisotropic index was 86/1000. At low sodium ion concentration (90-110 mequiv./l.) these anomalous,...

Chlorinated solvents are the most prevalent organic contaminants found in ground water (Stroo et al. 2003), and in the dissolved phase they are typically mobile and recalcitrant, particularly trichloroethylene (TCE) and tetrachloroethylene (PCE). Schwille (1984, 1988) was the first to recognize that chlorinated solvent plumes (i.e., zones of dissolved phase contaminants) are caused by immobile ...

We wish to report a case of lymphangioleiomyomatosis in an 86-yr-old female who presented with acute breathlessness on a background of increasing dyspnoea over a 3-yr period. She had been told that she had chronic obstructive pulmonary disease 2 yrs prior to this presentation, despite having never smoked. At the time of admission she was taking regular nebulised salbutamol but no other respirat...

OBJECTIVE To investigate whether fatal accidents, including drownings, have decreased among Icelandic fishermen and seamen. DESIGN Historical prospective study. The study population was record linked with the National Register and the Register of Deceased to get information on water transport accidents (ICD-7, E850-E858) during the period 1966-86. The number of persons in each calendar year a...
